Heathrow Airport plans to reopen Terminal 4 to passenger flights by July 2022.
Terminals 3 & 4 were originally closed in 2020 as the airport consolidated flights in Terminals 2 & 5 in response to the COVID-19 pandemic.
There were doubts as to whether Terminal 4 would ever reopen. Before COVID-19, it hosted a relatively small number of daily flights.
Terminal 4 is also not an easy location for airlines to operate from as it’s situated south of Heathrow’s two runways.
Whilst the UK government’s “Red List” was in place, Terminal 4 did act as an arrivals terminal for passengers arriving from red list countries.
Which Airlines Will Return To Terminal 4?
Heathrow is yet to indicate which airlines may return to Terminal 4.
Before COVID-19, Terminal 4 hosted primarily members of the Skyteam alliance and airlines not aligned to an alliance.
Some former occupants such as Air France and KLM are expected to stay in Terminal 3 to benefit from colocation with their joint business partner Virgin Atlantic.
Qatar Airways may also wish to stay in Terminal 5 to colocate with its IAG & Oneworld alliance partners.
Other former occupants of Terminal 4 included Air Malta, El Al, Etihad Airways, Kenya Airways, Kuwait Airways, Korean Air, Malaysia Airlines and Middle East Airlines (MEA).
There is also the question of passenger facilities. Whilst Terminal 4 hosted a number of passenger lounges, it will be for individual airlines and lounge operators to decide whether these are worth reopening.
Transport for London is also to confirm when London Underground services to Terminal 4 station will restart.
